Definitions
- the present invention relates to an oil-impregnated capacitor. More particularly, it is concerned with a capacitor impregnated with aromatic hydrocarbons which contains 1-phenyl-1-methylphenylethane having a specific isomer ratio.
- CSV corona discharge start voltage
- CEV corona discharge extinction voltage
- the present invention resides in an oil-impregnated capacitor made by winding at least one plastic film impregnated with an electrical insulating oil comprising 1-phenyl-1-methylphenylethane in which 1-phenyl-1-(4-methylphenyl)ethane and 1-phenyl-1-(2-methylphenyl)ethane are present in amounts of not less than 70 percent and not more than 15 percent, respectively, based on the total weight of the 1-phenyl-1-methylphenylethane.
- the PTE prefferably has the following isomer composition; not less than 70 wt.% (in PTE) of 1-phenyl-1-(4-methylphenyl)ethane (hereinafter referred to as "p-isomer”) and not more than 15 wt.% (in PTE) of 1-phenyl-1-(2-methylphenyl)ethane (hereinafter referred to as "o-isomer").
- the typical composition is 70-90 wt.% of p-isomer, 2-15 wt.% of o-isomer and 2-30 wt.% of m-isomer.
- the electrical insulating oil of the present invention may contain aromatic hydrocarbons other than the PTE.
- the PTE content is preferably 30 to 100 wt.%, more preferably 30 to 80 wt.%, based on the total weight of the insulating oil.
- the aromatic hydrocarbon preferably used in combination with the PTE in the present invention is an aromatic hydrocarbon having two condensed or noncondensed type aromatic rings, except PTE.
- Examples are diarylalkanes, alkylbiphenyls and alkylnaphthalenes.
- diarylalkanes are mentioned 1-phenyl-1-(dimethylphenyl)ethane, 1,1-di(methylphenyl)-ethane, 1-phenyl-l-ethylphenylethane, 1-phenyl-1-isopropylphenylethane, 1-phenyl-2-isopropylphenylethane, diphenylmethane, methylphenyl-phenylmethane, di(methylphenyl)methane, dimethylphenyl-phenylmethane, ethylphenyl-phenylmethane, and isopropylphenyl- phenylmethane.
- alkylbiphenyls are mentioned monoisopropylbiphenyl and diisopropylbiphenyl.
- alkylnaphthalenes are mentioned monoisopropylnaphthalene and diisopropylnaphthalene.
- the capacitor of the present invention is made by winding both a metallic foil such as an aluminum foil as an electrode and a plastic film to form a capacitor element and then impregnating it with an electrical insulating oil in a known manner.
- plastic film there is used such a film as a polyester, polyvinylidene fluoride or polyolefin film.
- a polyolefin film and particularly preferred is a polypropylene film.
- An insulating paper may be used together with the plastic film.
- a metallized film capacitor made by winding a metallized plastic film with a metal such as zinc vapor-deposited thereon is also included in the present invention.
- the oil-impregnated capacitor of the present invention can have a sufficiently long service life and fulfill a superior performance even at a temperature as low as -50°C.
- the oil-impregnated capacitors thus obtained were each electrically charged at a.potential gradient of 70 V/p at a low temperature of -50°C, and the time until breakdown of each capacitor was determined. More specifically, with respect to one insulating oil there were prepared ten capacitors impregnated therewith and their breaking times were determined, then out of ten measured values obtained, the highest and lowest values were excluded and a mean value of the remaining eight measured values was used as a breaking time of the capacitor concerned. Results are as set out in Table 1. Experiment-II
- the insulating oil Nos. 6 and 9 in Table 2 is the same as the insulating oil Nos. 6 and 9 in Table 1.
- the viscosity of PTE is changed according to isomer ratios.
- the viscosity of No.6 oil in Table 1 and 2, for example, is 4.0 cst at 30°C.
- PTE having the same isomer ratio as that shown in No.6 in Table 3 was mixed in various ratios with PXE, monoisopropylbiphenyl (MIPB hereinafter, trade name: TANATEX CG, product of SYBRON Co., Ltd.), diisopropylnaphthalene (DISN hereinafter, trade name: KIS-400, a product of Kureha Chemical Industry Co., Ltd.) and 1-phenyl-2-isopropylphenylethane (PIPE hereinafter, trade name: KIS-1000, a product of Kureha Chemical Industry Co., Ltd.), to prepare electrical insulating oils.
- MIPB monoisopropylbiphenyl
- DISN diisopropylnaphthalene
- KIS-400 1-phenyl-2-isopropylphenylethane
- PIPE 1-phenyl-2-isopropylphenylethane
- capacitor element Two polypropylene films each 14 u thick were put one upon another and the resulting laminate was wound together with a 7 p thick aluminum'foil as an electrode to obtain a capacitor element.
- the capacitor element was impregnated with each of the above electrical insulating oils in a known manner to obtain oil-impregnated capacitors each having a capacity of about 0.4 ⁇ F.
- the oil-impregnated capacitors thus obtained were each electrically charged at a potential gradient of 70 V/u at a low temperature of -50°C, and the time until breakdown of each capacitor was determined. More specifically, with respect to one insulating oil there were prepared ten capacitors impregnated therewith and their breaking times were determined, then out of ten measured values obtained, the highest and lowest values were excluded and a mean value of the remaining eight measured values was used as a breaking time of the capacitor concerned.
